nomah and State of Oregon, have invented.

certain new and useful Improvements in Computing Mechanism, of which the following is a specification. I

My present invention relates to computing mechanism, and more particularly to,

what is known -as the register or totalizer of a writing-adding machine wherein the operation ofthe register is controlled from the writing mechanism and serves to totalize a column of numbers as the latter are written upon a work sheet.

The object of the invention, stated generally, is to simplify the construction of the register and to render the operation of the same more certain and positive to the end that the possibility of error in the computation effected may be eliminated.

Considered more specifically one object of the invention-is to reduce the number of parts by equipping the selective and carrying mechanisms with operating springs common to both. 7

Another object is to provide 'means whereby the carrying dogs will be positively moved into engagement with the wheels by the operation of the carrying mechanism, instead of requiring independently operating dog locating mechanism, and whereby the dogs will be retained in their engaging positions during the entire carrying operation.

Another object is to so arrange the dog locating mechanism that while the location of the dogs with relation to the wheels is effected by the operation of the carrying mechanism, said dogs will nevertheless be allowed to move back out of engagement with the wheels whenever the carrying mechanism is retracted. A further object is to simplify and improve the resetting mechanism for the carrying devices and to provide improved means for adjustably securing the register in proper position to totalize a column located at any desired point on the work sheet. The means whereby these and other objects of the invention are attained will be clearly understood as the succeeding description is developed. i

In the accompanying drawings Figure 1 is a longitudinal sectional view through the register with the parts thereof occupying their normal positions.

It may be stated by way of premise that the writin -adding machine to the improvement of w ich the present invention is more particularly directed is a combined" typewriting and adding machine known to commerce as the Elliott-Fisher and fully disclosed in Patent No. 829,971 to Charles F. Laganke and-John A. Smith, although it is obvious that the herein described register construction is useful in other relations.

The Elliott-Fisher writing-adding machine is a flat platen typewriter including traveling printing mechanism operated by keys which also operate an actuator or master wheel. This master wheel coacts with a register or totalizer mounted on the frame of the typewriter in rear of the carriage. The register includes a series of denominational members in the form' of wheels. These members or wheels are engaged successively by ,the master wheel or actuator as the printing mechanism moves across the column to successive denominational positions. Whenever a number is printed in any denominational position on the work sheet the number wheel of the register occupying a corresponding denominational position will be rotated a number of units or increments corresponding to the value of the printed digits. The register also includes carrying mechanism whereby the'value accumulated in any denominational order is transferred to the next higher order when the limit of the order is reached. It will thus be seen that as a column of numbers is written on the work sheet by the typewriter the values represented by such numbers will be added by the register and the total exhibited. Since the machine thus briefly described is well known further description thereof appears to be unnecessary for the purpose of this disclosure.

In the drawings 1 indicates a portion of the typewriter carriage and 2 a portion of the master wheel or actuator. In rear of the carriage 1 is mounted the register 3 adjustable on the register bar 4 which is secured to the frame of the typewriter. The register includes a casing 5 the bottom wall 6 of which is formed with a transverse dove- Y tail channel or way 7 for the reception of the correspondingly shaped registenbar 4. Extending rearwardly from the channel or way 7 isa guideway 8 for the reception of a longitudinally flanged locking slide 9 to the under side of which is secured a plate 10 the front end of which is formed with teeth 11 arranged to engage the interdental spaces of a rack bar 12 adjustably secured to the under side of the register bar 4 as by screws 13. The rear end of the plate 10 is formed with a handle or finger piece 1 1 by means of which the slide may be moved longitudinally to effect the engagement and disengagement of the locking slide and rack. While the plate 10 may be made integral with the slide, it is secured thereto in the present instance by screws 15 one of-which is extended into a longitudinal slot 16 in the wall 5 and serves .as' a limiting stop for the slide.

The manner in which the adjustment of the rack 12 is secured is not material, the expedient here shown consisting in slotting the rack, as indicated at 17, for the accommodatlon of the securing screws 13 which, when the rack has been properly adjusted are screwed securely in place, the heads thereof impinging against the under side of the rack.

For the purpose of securely retaining the locklng slide in engagement with the rack, I provide securing means in the form of a yoke 18 the side arms of which are pivotally connected to the sides of the bottom plate 5 by hearing screws 19, the plate 5 Being preferably recessed, as indicated at 20,'to accommodate this yoke. Through the crossbar of the yoke 18 is passed a headed thrust screw 21 having a nut22 secured to its mner end and adapted to bear against the outer end of the slide 9. The inner ends 23 of the yoke 18 are extended sufliciently beyond the axis of movement thereof to constitute stops engaging the-bottom of the recess 8 to prevent the yoke from swinging down beyond a position in line with the slide. When it is desired to remove the yoke from interfering relation with the shde the former may be swung up, its side arms being recessed, as indicated at 24, to

accommodate the adjacent corner of the register casing. It may be remarked in passmg that'the -thrust screw 21 is not absolutely necessary to the operativeness of the structure, 811108 a slide and yoke of proper dimensions would coact to produce an absolutely secure lock for the register. By providmg the screw, however, wear mav be compensated for and in addition the slide may be forced to its engaging position under pressure.

{it the upper front corner of the register casing 1s formed a hood 25 having a sight opemng 26 through which is visible the number'reglstered by a series of registering wheels 27 mounted on the shaft 28 extendmg between the side walls 29 of the casing. The wheels 27 are toothed and have the numerals O to 9 displayed on their peripheries so that as a given wheel is rotated the digits thereon will be successively displayed at the open ng 26. Meshin with the wheels 27 1s a sub acent series 0 number wheels or denominational members 30 toothed to engage the registering wheels 27 and the master actuator The master wheel or actuator 2 1s moved lnto engagement with successive wheels 30 by the advance of the typewriter carriage 1 as heretofore intimated. The wheels 30 areyieldingly retained by wheel locators' 32 urged toward the wheels by springs 33 secured to a hook plate 34 secasing.

At the upper edge of the plate 35 are formed integralforwardly extending lugs 36 which engage the interdental spaces of the master wheel and serveto properly locate tain ter upon the completion of a cycle of movement by each number wheel, the adjacent number wheel of higher order is advanced a single increment, includes a series of carrying levers 37 mounted on a shaft 38 extending across the casing. The levers 37 are formed-at their front ends with locking portions 39 in rear of which are loosely mounted pendent carrying dogs 40 normally occupymg positlons in rear of and out of engagement with the wheels 30. The carrying levers 37 are also provided with upstanding tail pieces 41terminating in hobks 42 for the'attachment of motor springs 43 which serve, when permitted, to throw down the front ends of the carrying levers 37 for the purpose of causing the dogs 40 to operate the wheels 30. Normally, however, the levers 37 are retained in elevated positions, as shown in Fig. 1, by a series of triangw lar plates, latches or selectors 44 swung from a transverse shaft 45 and alternating with the levers 37. The lower ends of the selectors are bent laterally, as indicated at 46, to engage under the levers 37, but when the selectors are thrown back, the retaining ends 46 thereof come opposite recesses 47 in the levers 37 and permit the latter to drop from the position shown in Fig. 1 to that shown in Fig. 3 of the' drawings. The selectors or latches 44 are operated by the wheels 30.

The front end of each selector 44 is ex- 44 is effected in opposition to the springs 43, attention being particularly directed to the fact that these springs are secured at their front ends to hooks 49 extended from the selectors above but adjacent to the axis of movement thereof. The described arrangement serves to make the springs 43 common to both the carrying levers and selectors. This economical and exceedingly advantageous arrangement is made possible notwithstanding the fact that the springs 43 are required to exert'more or less force for the operation of the carrying levers and are not designed to .exert more than sufiicient force upon the selectors 44 to return them to normal position. These conditions are answered by the securing of the springs 43 wheels.

at some distance from the-axis of the carrying levers 37 to obtain considerable leverage, and very close to the axis of the selectors 44 to reduce the leverage sufliciently to carrying dogs 40 are normally out of engagement with the wheels 30 but engage and advance the latter when the levers 37 are swung down. Several forms of mechanism have heretofore been devised for effecting the engagement of the dogs with the For instance, the dogs have been urged toward the wheels by sprin s, (see Patent No. 825,469 to Laganke and mith),

but this mode is not only unreliable but as the dogs are urged toward the wheels during the retraction of the levers'37 as'well as during their operative movement there is a tendency to rotate the wheels 30 in the reverse direction whenever the carrying mechanism is reset. Another form of dog locating mechanism heretofore employed (see same patent) contemplates the elimination of the springs and the substitution of positively operated dog locators mounted within the register casing and extended in front thereof for engagement with an operating device mounted on the typewriter carriage. This arrangement while more reliable than the springs is open to the objection that the coacting parts on the register and carriage respectively must be carefully adjusted in order to insure their proper 00- action and furthermore the resettin of the carrying mechanism with the carriage lo cated -in certain positions is impossible because of the fact that the dogs are held positively in their forward or engaging positions as long as the part on the typewriter carriage is in coacting relation with the 10- catorsl 1 One of the objects of the present invention is to provide the register with positive dog locating means which, while leaving the dogs 40 disengaged from the wheels 30 both normally and during the retraction of the carrying mechanism, will operate positively and independently of the typewriter carriage, or a part carried thereby, to move the dogs into engagement with the wheels whenever the carrying mechanism comes into action. To this end the dogs 40 are formed at their lower ends with cam faces 50n0rmally located above, and in coacting relation with a normally stationary transverse member 51 constituting an element of a dog locating yoke 52 mounted on a transverse shaft 53. To reduce the friction the transverse member 51 of the yoke is preferably provided with a roller 54 with which the dogs 40 directly engage. Normally the dogs 40 occupy the positions shown in Fi l and are entirely out of engagement wit the wheels 30. As soon, however, as a selector 44 is thrown back, as indicated in Fig. 2, the carrying lever 37 controlled by said selector will be thrown down to the position indicated in Fig. 3. The first part of this movement will cause the carrying dog 40' carried by the lever to be cammed into engagement with a tooth of the adjacent wheel 30 by reason of a coaotion between the cam face 50 of the dog and the transverse member 51 of the yoke 52. This forward or engaging movement of the dog will take place during the initial movement of the lever 37 and continued movement of the lever will therefore effect the advance of the wheel 30 a single increment or unit of movement. It will be noted, however, that if the yoke 52 retained its normal position during the elevation or retraction of the carrying lever 37 the dog would be held in engagement with the wheel during such retraction and thus cause the wheel to be moved backward. Therefore, provision is made for moving the yoke 52 for the purpose of withdrawing the transverse dog-locating member 51 thereof rearwardly preparatory to the resetting of the carrying mechanism so that the dogs 40, when moved up with the levers 37, may be swung back out of engagement with the wheels 30. To secure this operation of the yoke 52 one of the side members thereof is provided with an arm 55 having a downturned extremity 56 which normally rests upon the upper surface of a reset slide 57 supported by the bottom wall of the register casing and projected through the front wall thereof for 00- action with the usual resetting cam movable with the carriage 1.

In the upper surface of the slide 57 is formed a depression 58 normally occupying a position in advance of the end ofthe arm 55 but adapted to receive said arm when the slide is moved back from the position shown in Fig. 1 to that shown in Fig. 4. The slide 57 is prevented from rising by a transverse bar 59 extending between a pair of side flanges 60 upstanding from the bottom wall 6 of the register casing and serving as seat flanges for the side walls 29. The slide 57 is disposed against the inner face of one of these flanges 60 and beam at its opposite side against an anti-friction thrust-roller 61 mounted on a screw 62secured in the wall 6. The roller 61 is located adjacent to the front end of the register casing and takes the side thrust of the slide 57 when the front end of the latter is engaged by the reset cam during theretraction of the carriage 1.

In addition to the recess or depression 58 the slide 57 is provided with a lateral lug or pin 63 engaging the forward extremity of an arm 64 of a reset rocker 65 mounted on the shaft 53 between the side'arms of the yoke 52 and adapted to be operated by the slide 57 to reset the carrying mechanism. The mounting of the yoke 52 and the rocker 65 is clearly shown in Fig. 1 of the drawings and these elements are shown in detail in Figs. 2 and 2".

Assuming the parts to be in the positions indicated in Fig. 3, the resetting of the carrying mechanism is effected by the rearward movement of the slide 57. The initial rearward movement of the slide permits the arm 55 to drop into the recess 58 and swings the rocker 65 into engagement with the carrying levers 37. This permits the locking yoke 52 to rock back away from the carrying dogs 40 So that the latter will not re-- verse or rotate the wheels 30 as the dogs rise with the carrying levers 37 as the latter are elevated by the rocker 65' during-continued rearward movement of the slide 57, see Fig. 4. The reset rocker 65 not only elevates the carrying levers 37 to normal position, but also engages and restores the selectors 44 to guard against any possible failure of the springs 43 to properly reset the selectors. When the slide 57 again moves forward, the arm 55 of the locating yoke is cammed out of the recess 58 and the yoke is thus presented in normal position to properly locate the dogs 40 when the carrying mechanism is again operated. V

The mechanism whereby the wheels are reset to zero after a column has been added is in most respects ordinary. The shaft 31 is equipped with resetting cams 66 designed to engage reset'pawls 67 carried by the wheels 30. At one end of the shaft 31 is secured a pinion 68 engaged by a toothed segment 69 formed at the rear end of a resetting lever 70 fulcrumed at one side of the casing. The resetting lever 70 is provided with a cam 71 engaging one arm 72 of. what is known as the resetting crank 73 swung from a transverse shaft 74 and having its other or long arm 75 forked to engage a projection or slide 57.

The s ecific construction of the resetting crank 73 is one of the features of this invention. It includes two side members 73 and 73*, the former being. in the form of a pin 76 at the rear end of the bell crank lever one arm of which forms the". A

forms the long arm 75 of the crank. The

members 73 and 73 are spaced apart by one or more spacing members 73" retained in place by a pin 73 passed through the members and spacing means respectively, as shown in Fig. 2. The shaft 74 serves as additional means for securing these elements of the crank since it passes through both side members and the spacing devices 73. In order that the utility of this construction may appear it may be stated that since the member 73 of the resetting crank coacts with the resetting lever it lies closely adj acent to one side of the casing and this may be either side, since in some forms of regis ters the resetting leveris located at one side and in others at the opposite side. The resetting slide 57 is not located immediately adjacent to either side of the casing, but is disposed at an intermediate point and therefore asthe registers vary in width and as the location of the resetting slide is usually uniform with respect to one side or the other of the casing, it is necessary to provide for readily changing the lateral dimensions of the resetting crank to accommodate the latter to the particular register under consideration. 1

It will be readily observed by reference to Fig. 2 that the member 7 3 of the crank may be placed either at the right hand or left hand side of the member 73 and the distance between the members may be increased or decreased by increasing or decreasing the number of spacing members 73 employed. In this way stock parts may be made to accommodate themselves to registers of all widths and also registers having the resetting lever located at either the right or .lefthand side.

The operation of the described mechanism may be stated briefly as follows:

As a number is printed by the depression of the typewriter keys in the usual manner, the master wheel 2 will rotate the number wheels 30 and the number will be exhibited by the registering wheels 27 at the sight opening 26. As the next number is printed the register will be again operated and the registering wheels will exhibit the total of the numbers written. When any one of the registering wheels 27 reaches the limit of the denomination which it represents, as for instance when it moves from 9 to 0, the carrying lug 48 of the-associated number wheel 30 will engage the adjacent selector 44 and swing the latter back to the position indicated in Fig. 2. This will release the carrying lever 37 of the next higher number wheel 30 and permit the former to drop to the position shown in Fig. 3. The dropping of the carrying lever will cause the carrying dog thereof to ride down past the transverse bar 51 of the locating yoke 52 which bar will cause the dog to be swung forward or cammed into engagement with a tooth of the wheel 30 and insure the carrying or advance of the latter by the continued downward movement of the dog.

When the carriage is retracted after a number has been written the reset slide 57 is moved back in a manner well understood in the art, thus swinging the reset rocker and permitting the arm 55 of the locating yoke 52 to drop into the recess 58. Continued movement of the slide 57 will cause the rocker 65 to restore the carrying mechan1sm to normal position. The dogs 40, however, of the carrying levers instead of being held in their forward positions, are allowed to rise while out of contact with the wheels 30 because as soon as the arm 55 of the locating yoke 52 drops into the recess 58 the yoke is swung back sufliciently to al-' low the dogs 40 to swing out of the wheels. It may be remarked in passing that by reason of the described action of the dog locat ing yoke the mechanism may be said to include dog locating means serving upon the operation of the carrying mechanism to insure the positive engagement of the carrying dogs with the number wheels and automatically withdrawn from normal position to permit the disengagement of the wheels and dogs during the resetting of the carrying mechanism.

After a computation has been completed, the register is reset to zero by the manipulation of the resetting lever 70. This is ef fected by elevating the rear end of the lever thus causing the toothed segment 69 thereof to rotate the pinion 68, the shaft 31, and the cams 66, the latter picking up the pawls 67 and rotating the wheels 30. to zero. in a I manner well understood in the art. It frequently happens, however, that when it is desired to reset the register one or more of the wheels 30'will be locked by the looking ends 39 of certain depressed or operated carrying levers 37, see for instance Fig. 3. It is therefore necessary to provide for the resetting of the carrying mechanismthrough the instrumentality of the lever 70. It is for this reason that the resetting crank 73 is connected to the slide 57 and arranged to be operated by the cam 71 of the lever 70. When the lever 70 is first moved, for instance to'the position indicated in Fig.4, the crank 73' will be swung to retract the slide 57 and thus cause the resetting of the carrying mechanism in a manner heretofore described in connection with the retraction of the slide by a cam movable with the carriage. Obviously the wheels 30 may begin to rotate as soon as the levers 37 begin to rise and when the lever 30 has reached its limit of movement, as shown in Fig. 5, the wheels will all have been set to zero and held locked by the levers 37, which obviously will have been operated in a manner here tofore described during the movement of the wheels 30 from 9 to 0. It is now merely necessary to return the lever 70 to normal position and incidental to this movement the cam 71 will again engage the resetting crank 73, as shown in Fig. 6, swinging the latter to operate the slide 58 and thus again reset the carrying mechanism, the cam -H finally passing beyond the arm 72 of the crank 73 permitting the latter, the reset slide 77, the reset rocker 65 and the dog locating yoke 52, to resume their normal positions, as shown in Fig. 1.

It is thought that from the foregoing, the construction and arrangement of the regis ter embodying my improvements will be clearly understood, but while the present embodiment of the invention appears at this time to be preferable, I wish to reserve the right to effect such variations of the illustrated structure -as may come fairly within the scope of the protection prayed.
